View source for Module talk:Interlinear

== Intro ==
This is an organically grown module: it started out small and simple, but over time various bits got added, then rewritten and trimmed, all at different times and in different styles, so the result is probably quite unreadable. Be warned before approaching the code.

The major items I've got on the to-do list are (sorry, no improvements in readability down the pipe!):
* Revamp styles and classes in accordance with [[mw:Extension:TemplateStyles]], whenever that extension becomes available on the English wikipedia (check at [[Special:Version]])
* Make lang= invoke [[Module:Lang]], whenever that has settled
* Rewrite the bletcherous parser function. This will make more sense if done at a time when we will be able to use (as an extension or a module) either an XML parser, or at least a proper regex engine.
All these things are dependent on the presence of external factors, so the main task at the moment is to wait until they become available. – [[User talk:Uanfala|Uanfala (talk)]] 20:28, 12 December 2017 (UTC)

== Automatic transliteration ==

I really like what the module does. I'm experimenting with using it for Ancient Greek example sentences in [[User:Erutuon/Ancient_Greek interlinear glossing]], though it might not be used in articles anytime soon because it's untraditional &ndash; not typically used in teaching Ancient Greek.

So, the Ancient Greek examples have automatically generated transliteration, which I enter by copying the Greek text into {{temp|grc-tr-bare}} in a separate parameter from the Greek text, but I was thinking that perhaps the module could use the transliteration module ([[Module:Ancient Greek]]) to automatically generate transliteration, retrieving the name of the module and the name of the exported function for the language from a table. That would be more convenient.

For example, from this method of inputting the example &ndash;
<div style="margin-left:1.5em;">
{{demo|br=0|<nowiki>{{fs interlinear|lang=grc
|'''Σωκράτ-ης''' γὰρ '''σοφ-ὸς''' ἦν καὶ '''δίκαι-ος'''
|{{grc-tr-bare|'''Σωκράτ-ης''' γὰρ '''σοφ-ὸς''' ἦν καὶ '''δίκαι-ος'''.}}
|Socrates-NOM.SG for wise-NOM.SG be.IMPERF.3.SG and just-NOM.SG.
|For '''Socrates''' was '''wise''' and '''just'''.
}}</nowiki>}}</div>

&ndash; to this &ndash;

<div style="margin-left:1.5em;">
{{demo|br=0|<nowiki>{{fs interlinear|lang=grc
|'''Σωκράτ-ης''' γὰρ '''σοφ-ὸς''' ἦν καὶ '''δίκαι-ος'''
|Socrates-NOM.SG for wise-NOM.SG be.IMPERF.3.SG and just-NOM.SG.
|For '''Socrates''' was '''wise''' and '''just'''.
}}
</nowiki>}}</div>

&ndash; but with the transliteration automatically generated.

Anyway, it's an idea. It is probably not time to try to implement it, as Ancient Greek isn't using the template in entries yet. — [[User:Erutuon|Eru]]·[[User talk:Erutuon|tuon]] 08:59, 23 January 2018 (UTC)
:I've added a very tentative version of the functionality you've described. It only works from {{tl|fs interlinear}}:
<div style="margin-left:1.5em;">
{{demo|br=0|<nowiki>{{fs interlinear|lang=grc
|'''Σωκράτ-ης''' γὰρ '''σοφ-ὸς''' ἦν καὶ '''δίκαι-ος'''
|auto
|Socrates-NOM.SG for wise-NOM.SG be.IMPERF.3.SG and just-NOM.SG.
|For '''Socrates''' was '''wise''' and '''just'''.
}}
</nowiki>}}</div>

:If a line supplied by the template is the string "auto" then that line is replaced by the automatic transliteration of the preceding line. How is that for usability? The alternative from your examples is for the module to guess from the total number of lines supplied (if there are three instead of the expected four) and to assume that it's the first line that needs to be transliterated. These are reasonable assumptions most of the time, but I think they will make it unreasonably difficult to use the feature in other contexts (say, if there are source sentences in more than one language or script, with each needing to be transliterated). What do you think? If the word "auto" can be replaced with something more intuitive, go ahead. The actual transliteration happens in {{code|function transliterate}}. Feel free to pick that up from where I've left it.

:As it's currently set up, the transliterator is chosen based on the lang code (if the source sentene is the ''n''th unnamed parameter, then first {{para|lang''N''}} is looked up and if it's missing then {{para|lang}} is used). I don't know if it's reasonable to try to make the module guess based on the script used. Ultimately, I guess there should be support for different transliteration schemes, as well as for backward transliteration (from a Roman-based scheme into a foreign script).

:Given that automatic transliteration is not needed solely in interlinear glosses, I think there should be an umbrella metamodule to handle all automatic tranlsiterations, loading modules for individual scripts/languages as and when required. Any thoughts? – [[User talk:Uanfala|Uanfala (talk)]] 03:38, 27 January 2018 (UTC)

== Argument scenarios ==

What's the right thing to do when there are fewer than 3 arguments? The documentation is conflicting on this point.

{|class="wikitable" style="text-align: center;"
!
! 1 arg
! 2 args
! 3 args
|-
! Line 1
| style="background-color: lightgreen;" | No Italics<br />Spacing<br />Glossing
| style="background-color: lightyellow;" | Italics??<br />Spacing<br />No Glossing??
| style="background-color: lightgreen;" | Italics<br />Spacing<br />No Glossing
|-
! Line 2
| —
| style="background-color: lightyellow;" | No Italics??<br />Spacing??<br />Glossing??
| style="background-color: lightgreen;" | No Italics<br />Spacing<br />Glossing
|-
! Line 3
| —
| —
| style="background-color: lightgreen;" | No Italics<br />No Spacing<br />No Glossing
|}

In particular, if there are only 2 arguments (lines), what do the first and second ones most likely represent? I would say native language + gloss, but the current implementation appears to be native language + free translation. (IMO, if you're not actually glossing, why use this template in the first place? The first line would have special spacing for no reason.) Thoughts? &mdash;'''[[User:GPHemsley|Gordon P. Hemsley]]'''&rarr;<span style="font-size: larger;">[[User talk:GPHemsley|&#x2709;]]</span> 12:35, 11 July 2019 (UTC)
*The relevant part of the documentation is in the last paragraph of [[Template:Interlinear#Basic usage]]. Given that the module can be used with any number of lines, I thought it was simpler to have one rule for all cases of more than one line: 1a) the last line is treated as the free translation and so isn't interlinearised; 1b) to omit a free translation, supply an empty last line. I agree that for two lines it's almost certain the intended use is native language + gloss, so it's possible to add an exception for this case, but doing so would add an extra rule that users may need to know. It will also make it impossible to format two lines as native language + free translation, so we must be completely sure this is never going to be needed. – [[User talk:Uanfala|Uanfala (talk)]] 22:52, 11 July 2019 (UTC)
::The conflict is that [[Template:Interlinear#Glossing abbreviations]] states that the second line will be assumed to be glossing if no glossing line is specified – so the problem arises of what happens when the second line and the last line are the same line. It may turn out that this is simply a matter of clarifying the documentation. (Admittedly, despite multiple attempts to find such information, I missed the part where it says how to force the last line to be interlinearized. It might be worth making that stand out more and/or putting it in multiple sections.) &mdash;'''[[User:GPHemsley|Gordon P. Hemsley]]'''&rarr;<span style="font-size: larger;">[[User talk:GPHemsley|&#x2709;]]</span> 11:42, 12 July 2019 (UTC)
:::Oh, I see, I hadn't noticed that. So it turns out we have extra complexity either way: either it's assumed the second line contains glosses {{under|unless there are altogether only two lines}}, or the last line is always assumed to be the free translation {{under|unless the last line is the second line}}. So we need to either change the behaviour of the module, or update the documentation. Both changes are trivial to make, so the question is which of the two alternatives results in greater usability. Any thoughts? – [[User talk:Uanfala|Uanfala (talk)]] 12:36, 12 July 2019 (UTC)
::::You raised an important point earlier about ''being completely sure'' that no one is going to want to format two lines as native language + free translation, and that gave me pause. However, I can't think of a valid scenario where you would want to interlinearize a single line of text up against a free translation. Which brings into question why the single line behavior is the way it is—are we able to find examples of single line interlinearization that we can conceive adding a line of free translation to? &mdash;'''[[User:GPHemsley|Gordon P. Hemsley]]'''&rarr;<span style="font-size: larger;">[[User talk:GPHemsley|&#x2709;]]</span> 21:56, 12 July 2019 (UTC)
{{od|:::::}}Yeah, there's no need to interlinearise if it's just a single line (so ''that'' aspect of the behaviour of the template will need to change). I guess the way I had envisaged that two-line use is for a native language sentence + free translation, without glosses. And that's kind of what's done in the two real-world examples I was able to find [https://en.wikipedia.org/w/index.php?title=User:Juliekallini/Yimas_Language&oldid=897099999#Stress] [https://en.wikipedia.org/w/index.php?title=Hmong_language&oldid=905977178#Mood]. In a way, there's no need for using this (or any other) template here. But if you need to use some of this template's bells and whistles (or if you don't, but are forced to for consistency with uses of the template in the same article), that will be difficult to do. An example:
{{interlinear|lang=ayz|number=1a)
|fai re-'''t'''-o
|woman specific.location-near-{{gcl|U|unmarked gender}}
|'this woman'}}
{{interlinear|lang=ayz|number=1b)
|fai re-'''f'''-o
|'this woman '''very''' near'}}

:Ah, interesting examples. It seems to me these would more intuitively marked up by leaving the ''second'' line blank for these examples—where the glossing is implied by context. What do you think about that inversion (opting out of the second line instead of opting out of the third line)? Other thoughts: (1) I agree there's little reason to use this template for single words, though I suppose there's no way or even reason to stop someone from trying. (2) Should/can we do something to normalize quotation marks around the free translation? &mdash;'''[[User:GPHemsley|Gordon P. Hemsley]]'''&rarr;<span style="font-size: larger;">[[User talk:GPHemsley|&#x2709;]]</span> 14:42, 13 July 2019 (UTC)
::Normalising quotation marks, as in making sure across wikipedia only one type is used, I'd assume the single one? I have no opinion on that and won't object if anyone does it.
::I hadn't thought of marking up the second line as blank, but now that you mention it, it does seem more intuitive in this particular case. But such a rule wouldn't scale up well to cases with more than three lines. An alternative I can think of is to change the default "glossing" line to be not the one that's second (counting from the start), but the one that's last but one. This seems like a good idea anyway: if there are many lines involved, the line with glosses is most likely to be the last one before the free translation, as extra lines are most often used to give several versions of the native text (different writing systems or transliterations, with or without morpheme breaks, etc.). What do you think? – [[User talk:Uanfala|Uanfala (talk)]] 18:07, 13 July 2019 (UTC)
:::I think that makes sense, from both perspectives. Lines 1 to (n−2) are interlinearized; line (n−1) is the gloss; line n is the free translation. Then n<3 becomes more obvious (n=1 would be free translation only; n=2 would be glossing + free translation), and it is easy to skip any section. Though this does bring back the question of why you would use this template with only one line.
:::Regarding quotation marks, I was pondering whether the free translation should be automatically wrapped in quotation marks, as opposed to added (or not added) by the author. I'm fine if we consider that separately, or not at all. &mdash;'''[[User:GPHemsley|Gordon P. Hemsley]]'''&rarr;<span style="font-size: larger;">[[User talk:GPHemsley|&#x2709;]]</span> 12:22, 14 July 2019 (UTC)
:::: Before you spelt it out, I guess I hadn't completely understood the obvious implication of the "glossing at n-2" rule for the case of n = 2. So that means glosses + free translation? I think that's probably the least likely way to use just two lines of "interlinear" text. But at least it makes the two likelier cases a lot more intuitive: want it without a free translation? – supply an empty last line; don't want a line of glosses? – let the second line be empty.
::::As for n = 1, I don't think anyone would expect {{tl|interlinear}} to do anything at all in this case. I've added this functionality because we generally do need a way to easily format a long string containing several grammatical abbreviations (as found in glosses): it's better to have the following example – {{interlinear|1SG.SUBJ-3SG.OBJ-mach-APPL}} – created like this:
:::::<code><nowiki>{{Some template|1SG.SUBJ-3SG.OBJ-mach-APPL}}</nowiki></code>, than like that:
:::::<code><nowiki>{{gcl|1SG}}.{{gcl|SUBJ}}-{{gcl|3SG}}.{{gcl|OBJ}}-mach-{{gcl|APPL}}</nowiki></code>.
::::It's good to have ''some'' template do that, and I reckoned it might be easier to let that be the same template that formats multiple-line glosses. It's not that counter-intuitive, and it doesn't get in the way of other people using the template with n>2. What do you think?
::::I don't think quotation marks should be automatically added to the free translation. Because it's not always ''just'' a free translation: the last, non-interlinearised, line can also contain explanations (in addition to or instead of a free translation) or references. – [[User talk:Uanfala|Uanfala (talk)]] 22:56, 16 July 2019 (UTC)

=== Proposed changes to behaviour with unusual numbers of lines ===
{{od|:::::}}Our goals here are two-fold, right?
# Make the template usage intuitive.
# Make the common case the default case.
So I think we're in agreement now about what to do with 3 arguments but only two lines: simply skip the one you don't want to use. Code-wise, that means implementing (in the general case) line n as free translation, line n−1 as gloss, lines 1 through n−2 as non-gloss interlinear. For n=1, special case that the single line is gloss. For n=2, where the third argument is not explicitly left blank (to the extent that that's possible to determine), we can special case whatever the most likely scenario is if it differs from the general case.

If it makes sense, we could even implement the logic such that the gloss is the core of the template, and the addition of more lines means building up or down. So, n=1 means just the core: glossing; n=2 means build up: non-gloss interlinear, glossing; n=3 means build up then down: non-gloss interlinear, glossing, free translation; n=4 means build up then down then up: non-gloss interlinear, non-gloss interlinear, glossing, free translation; and so on. Does that make sense? &mdash;'''[[User:GPHemsley|Gordon P. Hemsley]]'''&rarr;<span style="font-size: larger;">[[User talk:GPHemsley|&#x2709;]]</span> 11:41, 18 July 2019 (UTC)
: I really like the idea of the gloss being the core of the template. This seems to capture all the normal use cases in a single scheme. But I'm a bit concerned about usability: n-1 is an easy rule to remember, n/2 rounded down plus one – not so much so. – [[User talk:Uanfala|Uanfala (talk)]] 22:10, 21 July 2019 (UTC)
::I think if the template is built in a logical way, you won't need to remember the rule in order to have accurate intuitions about it. {{smiley|:)}} And besides, the rule need only be an implementation detail – I'm sure there are plenty of more easily memorized ways of explaining how to use it, including by making only minimal changes to the existing documentation.

{{od|:::::}}I admit that that edit is icky, but it was the quickest way to resolve an issue where explicitly specifying the same parameters as the defaults resulted in different output. (It was causing one or two of the new tests to fail.) There's probably a better way to fix that issue, but it would involve a broader refactoring of how things are output, which I didn't want to get into just yet.

I've been running the code through a linter to pick out some potential trouble points, and there are still a couple to address, but after that I'll look into what it would take to implement what we've laid out here. (I'm still working on familiarizing myself with both Lua and your code.)

=== Comment on proposal and parameter choices ===
{{ping|Uanfala}} You invited comment on "this proposal", which linked only to this page, but I take it you meant the subsection above "Proposed changes to behaviour with unusual numbers of lines"?  Now that I've read the entire page, and put that proposal in context, I do have a comment or two.
#First, congratulations! on just how good the {{tl|gcl}} and {{tl|interlinear}} are.  And sincerely, thanks for all the hard work you've done.
#Second, I'm so glad to see you inviting (and achieving) productive dialogue with other editors.  Seems that [[User:GPHemsley|Gordon P. Hemsley]] has already made substantial contributions and will likely have much to offer, both as a linguist user and a coder comfortable with HTML and its styling.  (Particularly impressed by his liking for [[test-driven development]]!)
#On the matter you asked about, as a rule I favour '''explicit parameters''', rather than implicit ones.  In the case at hand, that would mean providing an explicit name for each type of line in the interlinear, e.g. thus: <nowiki>{{interlinear[|source=<source-value>][|gloss=<gloss-value>][|literal-translation=<literal-value>][|free-translation=<free-value>]…}}</nowiki> with the code for each line having the form |''keyword'''n'''''=''value'''n''''', each ''keyword'''n''''' being a line-type literal, ''value'''n''''' its value, brackets ([…]) representing optional arguments, the asterisk (*) representing zero or more occurrences of the bracketed item and the ellipsis (…) representing all other defined line-types.
#Of course, any per-line override keywords could also be given (either as a reserved keyword, or as a keyword=value pair) between the pipes "|" that separate the lines, thus: <nowiki>{{interlinear|source=<source-value>[ <source-override-m>]*|gloss=<gloss-value>[ <gloss-override-m>]*|literal-translation=<literal-value>[ <literal-override-m>]*|free-translation=<free-value>[ <free-override-m>]*|…}}</nowiki>, with each ''m'' numbering the distinct override keywords, and similarly for any other defined line-types.
#The chief benefit of naming parameters explicitly is the avoidance of any ambiguity.  A consequence of this is that parameter ordering becomes much freer.

I'd be happy to hear your thoughts on using explicit vs. implicit parameters. {{ping|GPHemsley}} yours too.

[[User:Yahya Abdal-Aziz|yoyo]] ([[User talk:Yahya Abdal-Aziz|talk]]) 02:56, 5 September 2019 (UTC)
:Hi, {{u|Yahya Abdal-Aziz|yoyo}}, and thanks for joining in! Yes, having explicit, named parameters for the lines is definitely an option. I didn't initially go for it because the template was created around the idea of ease of use ''in the most common case'' (the canonical three lines). Any editor who needs to add a simple interlinearised example can just write one straight off, without having to go to the template documention to look up the exact names of the parameters. I feel that this simple device – invoking the template with three unnamed parameters to create the typical glossed example – should continue to be available whatever system is eventually adopted for the unusual cases (''n'' different from 3).
:As to how it should all be set up for these more unusual cases, I don't really have preferences and I would like to hear what others think. The current system – all additional lines continue to be unnamed parameters and there's often a need for overrides like {{para|glossing2|no}} – has the advantage of consistency with the simple case of n=3, but I'll have to admit it's not very elegant. If we switch to explicit parameters it will all be more transparent semantically, and that's good. But I don't know to what an extent it will be less complicated. At a minimum, the parameters for the line-types will need to be numbered (e.g. <code><nowiki>{{interlinear|source1=...|gloss2=...|literal-translation=...}}</nowiki></code>); this is to allow for non-canonical line orders (say, annotations before source text: <code><nowiki>{{interlinear|literal-translation1=..|source2=...|gloss3=...}}</nowiki></code>), and for multiple instances of each line type (<code><nowiki>{{interlinear|source1=...|source2=....|gloss3=...}}</nowiki></code>).

However, there are multiple issues with the display:
* The most glaring one is that the hieroglyphs (formatted using {{tag|hiero}}) are not properly supported, being correctly shown once and then incorrectly shown again without formatting.
* Smaller but still consequential issues are the failure to detect the boundaries of {{tag|ref}} and wikilinks in the glossing line, thereby failing to properly format 3SG and DUAL, respectively.
Additionally, attempting to identify the transliteration using either language code {{code|egy}} or script code {{code|Egyp}} results in an error about the transliteration scheme not being recognized, despite both being standard ways to use {{t|transl}}.

I have not investigated the cause of these issues, or any potential solutions, but I am happy to help with debugging and/or coding to get them fixed. &mdash;'''[[User:GPHemsley|Gordon P.

:Well, the module wasn't really meant to be used with text structured in such a complicated way. {{tag|hiero}} outputs html tables and they break the template in several ways. The immediate issue of the repeated hieroglyphs is down to the fact that at the end of the interlinear display the module outputs a hidden {{tag|p}} element containing the entirety of each line (that's for accessibility reasons). When the module tries to place the hierogyphs line (with all its tables) into a p element, it results in bad html, which gets corrected by moving the whole thing outside that element, and so the text gets exposed. This particular problem can be easily fixed by replacing {{code|div:tag("p")}} with {{code|div:tag("div")}} at line 787 of [https://en.wikipedia.org/w/index.php?title=Module:Interlinear&oldid=905929797 the current version of the module]. However, the visible interlinear display itself uses {{tag|p}} elements, so again the hieroglyphs fall out of that, with the result that they will slip out of the scope of any relevant parameters you've applied (like {{para|lang1}}). This can be fixed in a similar manner by making the interlinear display itself be rendered in {{tag|div}} elements rather than {{tag|p}} elements. I can't think off the top of my head of a reason why this could be a bad idea, but I'm not willing to make such a fundamental change without careful consideration.
:The real problem is that hieroglyphs, or any other vertical scripts, can never be made to work well within {{tl|interlinear}}. You might have noticed that the interlinear lines are vertically not well aligned: in the first word for example they reach a little bit lower than in the second word, that's because the first hieroglyph is a bit taller than the second one. I don't reckon there would be a way to fix that within the existing capabilities of the module. That's probably a case where the old method of doing glossed texts using tables actually works quite well. Of course, we ''could'' make the module detect hieroglyphs in the input and specifically format them using tables, but I think it's overall simpler if the few articles that need this just used wiki tables directly, as they do now.
:As for the refs stopping the gloss from getting formatted, and the standard script identifier not getting recognised – these aren't supposed to be happening. I'll definitely have a look when I have a bit more time. Now, the gloss not getting recognised inside a wikilink: that's not a bug. The parser deliberately avoids doing anything to text within links, partly because it's assumed that a user who manually adds a link might have more specific ideas and so not be happy with the default behaviour, and partly because the risk of accidentally breaking something is greater than the benefit of saving a bit of typing time. You can just enclose "DUAL" in either {{tl|sc}} or {{tl|gcl}}. – [[User talk:Uanfala|Uanfala (talk)]] 22:00, 21 July 2019 (UTC)

::I can look more deeply into the internals later on, but might CSS flexbox be useful for the vertical alignment issues? Surely support for vertical orthographies is something we should look into handling better (outside of the HTML issues caused by {{tag|hiero}}), no? Also, is repeating the text a second time really the best way to handle accessibility of glossing?

::::You'll be very welcome to look more closely. I know next to nothing about html, and the current html output is largely copied from another site (as documented [[Template_talk:Interlinear#HTML_output|here]]). – [[User talk:Uanfala|Uanfala (talk)]] 06:34, 22 July 2019 (UTC)
:::::I hadn't heard of flexbox before. I take it that you're better acquainted with html than me, so I'll leave that for you: if you come up a way to support vertical text that won't have undesirable consequences, you're welcome to try it out. Personally, I don't see that as a priority, as it's a really niche use: apart from hieroglyphs, I can only think of the Old Uyghur and related scripts that go vertically. I have to admit though, that my initial misgivings about the potential of the html of {{tag|hiero}} to break the template was misplaced. When the module processes wikitext, it sees the hieroglyphs not as html, but as [[meta:Strip marker|strip markers]], so it shouldn't have any more (or less) problems with them than it does with other extension tags, like {{tag|ref}}.
::::: As for accessibility, this again is an area in which I know next to nothing, so if you have any suggestions, I'm all ears. Repeating each line in a hidden div was simply copied from [http://bdchauvette.net/leipzig.js/ the external site] I used as a model. And I think it makes sense: in the the template's output, the elements go in the order word 1, gloss 1, word 2, gloss 2, etc. For people with screen readers, this makes the connection between each word and its gloss obvious. What it doesn't make obvious at all, is that the relations can go horizontally as well: word 1, word 2, etc, form a sentence.
::::: Just adding that I've been thinking it might be time to switch to using CSS classes (using [[Wikipedia:TemplateStyles|TemplateStyles]]), which should remove a lot of the clutter from the html output. – [[User talk:Uanfala|Uanfala (talk)]] 21:20, 23 July 2019 (UTC)
{{od|::::::}}It'd probably be good to wait until we've done the parameter work before we start on any of these major output changes, but I think we should figure out what the new output should ultimately look like before we start changing anything. I'm happy to take on the HTML and CSS aspects; I do have a lot of experience in those areas. As far as accessibility is concerned, I've been going back and forth between tables and flow content, trying to strike the right balance between semantic markup and display formatting. I haven't settled on a solution, and we'll probably need to iterate on this and solicit feedback, but I expect that duplicating the content is not the right way to go. (I'm not sure that having a screenreader read the content twice, once in each format, would not be the desired behavior, but perhaps I'm wrong.)

:Your help with the html will be greatly appreciated! I have to say that I wouln't mind even if fundamental aspects of it are re-examined; there certainly are other ways to format interlinear text: ''Glossa'' for instance uses {{tag|ol}} elements rather than divs ([https://www.glossa-journal.org/articles/10.5334/gjgl.582/ example]). – [[User talk:Uanfala|Uanfala (talk)]] 14:23, 26 July 2019 (UTC)


==Proposed feature: nested numbering==
Current module Interlinear only provides a linear numbering feature. I wish to use this module to write some linguistics examples that are in a nested list form. For example, I can make something like this using a plain table: 
{|
|+
|(1)
|
|Jacaltec (Mayan), VAP (VSO)
|- style="vertical-align: top;"
|
|a.
|{{interlinear
|xa' ix te' hum wet an 
|gave CL:she CL:the book to:me 1
|"She gave the book to me."}}
|- style="vertical-align: top;"
|
|b.
|{{interlinear
|xahtoj naj yiban no' cheh
|go:up CL:he on CL:the horse
|"He climbed on the horse."}}
|}
But this cannot be done using <code>numbering</code> parameter in the module. It would be great if such feature is implemented to the module. However, I do not have an expertise in Lua language nor do I have the authorization to edit a module, thus, I am leaving a proposal here. Thanks! --[[User:Benzenekim|Benzenekim]] ([[User talk:Benzenekim|talk]]) 10:27, 31 May 2020 (UTC)
{{od}}
{{u|Benzenekim}}, you could produce a similar result without using tables, and it's a lot simpler:{{br}}
(1) Jacaltec (Mayan), VAP (VSO)
{{interlinear|display-messages=no|number=a.
|xa' ix te' hum wet an 
|gave CL:she CL:the book to:me 1
|"She gave the book to me."}}
{{interlinear|display-messages=no|number=b.
|xahtoj naj yiban no' cheh
|go:up CL:he on CL:the horse
|"He climbed on the horse."}}
The trick is that the parameter accepts any string of characters, not just numbers, and that its name is {{para|number}} (not {{para|numbering}}, though I should probably add that as an alias; to be honest, I'm not completely happy with either parameter name, but haven't been able to come up with anything better). In the example, you can change the alignment by padding with {{tl|nbsp}} where necessary, though there probably are more elegant ways of doing that. Does that work for you? If your proposal is to make a single invocation of the template capable of rendering several interlinearly glossed texts, then that is technically possible, but not practicable as it will add way too much complexity. – [[User talk:Uanfala|Uanfala (talk)]] 15:31, 31 May 2020 (UTC)
: {{ping|Uanfala}} Thanks for the feedback!

== tooltip content with links ==

I was trying to use <nowiki>{{gcl}}</nowiki> with three unnamed arguments &mdash; in the example on [[Woods Cree#Morphology]] I wanted <code><nowiki>{{gcl|TA|transitive animate|Algonquian languages#Grammatical_features}}</nowiki></code> &mdash; but instead of showing argument #2 ("transitive animate") as the tooltip, it was showing the page title from the link ("Algonquian languages"). This seems to be a bug: argument #2 is being ignored. Or is there some other way to do what I wanted? [[User:4pq1injbok|4pq1injbok]] ([[User talk:4pq1injbok|talk]]) 10:17 22 January 2023 (UTC)
:Thanks for noticing this. It's definitely a bug. It can be fixed by changing the order in which the html elements are built up in format_gloss(), that's between lines 299 and 334 of the current version of the module. However, that's a bit finicky to do right away, so I'll leave it until I set off working on the next version of the module. It's going to be at least a couple of months until then. In the meantime, the somewhat clumsy workaround that you can use is: {{code|<nowiki>[[Algonquian languages#Grammatical features|{{gcl|TA|transitive animate}}]]</nowiki>}}. – [[User:Uanfala|Uanfala]] ([[User talk:Uanfala|talk]]) 13:27, 22 January 2023 (UTC)

Until now, the module could just load the section and then do things with it depending on whether it was empty or not. But now before loading the section, the module will have to first load the entire page and search its wikitext. The effect on performance seems to be small (I checked 15 times, and the average slowdown was 4%, probably not enough to make much of a difference at present), but it doesn't seem like the optimal long-term solution. Or is it that I'm using LST in ways it was not designed to be used? – [[User:Uanfala|Uanfala]] ([[User talk:Uanfala|talk]]) 20:07, 14 March 2023 (UTC)
:::::: {{U|Uanfala}}, thanks, now merged! we could experiment with doing the LST using string processing, instead of doing the <code>frame:preprocess</code> which may be faster, since we are now loading the page contents (see, for example, [[Module:Transcluder]]).  I could experiment with this if you think it would be useful.  I don't think you are necessarily using LST in a bad way, it's just that we have a new tracking category to find actual bad uses, which we are unable to distinguish from false positives.

=== Glyph order in words ===
Hello again Eievie: by "original-language word" I mean {{lang|phn|𐤀𐤔𐤌𐤍𐤏𐤆𐤓}} (ʾšmnʿzr, ʾèšmūnʿazar, Eshmunazar) etc.

In [https://grammar.katabiblon.com/?page=ph Kata Biblon] which you linked to (the table just above the match for "Phoenician and Greek transliteration") the transliterations are presented as currently in [[Sarcophagus of Eshmunazar II#English translation of the lid inscription]], with whole sentences in columns for the stages of transcription, transliteration and translation. Here we are considering having successive lines for each stage, with the individual words of the inscription, transliteration and transcription in separate columns, followed by a line for the translation. This makes it easier to see how each word is being transformed (the columns cannot apply to the translation since word disposition may change). This already works nicely for languages written left-to-right, but it becomes confusing for right-to-left languages since the order of letters in the transliteration etc. is reversed compared to the order of the corresponding glyphs in the original language.

Here is a use case where following this glyph-to-letter correspondence is needed:
: In [[Sarcophagus of Eshmunazar II#Inscriptions]], an example of Aramaic usage is given with Hebrew script and the transliteration. I wanted to add the corresponding Phoenician script but it seemed difficult to identify the correspondence. This would have been much easier if the corresponding glyphs and letters were in the same order in vertically aligned words.

Hardly any of our readers will be able to read such inscriptions fluently in the original script, so making it easy to compare one representation with another should have priority in this sort of comparison table. I agree that writing the transcriptions etc back-to-front would not be helpful! Thus reversing the whole original inscription is appropriate, but only in the context of this sort of word split table.

It is probably also important to present the inscription in its original correct form too. Your third example in [[Talk:Sarcophagus of Eshmunazar II#Lining up the pieces]] goes some way towards showing that: the display problem there is the excessive misalignment of the first line. -- [[user:Mirokado|Mirokado]] ([[user talk:Mirokado|talk]]) 17:19, 29 January 2024 (UTC)

:: Thanks again for your response. I have now investigated the template a bit more. If we reduce the width of the window, we can see that the interlinear display flows at smaller widths, thus supporting rather longer texts that in any of the examples we have been using. That means that what I have been thinking of would not work as well as I had hoped, so I have now struck point one above. -- [[user:Mirokado|Mirokado]] ([[user talk:Mirokado|talk]]) 22:44, 30 January 2024 (UTC)
:: I have looked at a couple of glossing rules ([https://www.eva.mpg.de/lingua/pdf/Glossing-Rules.pdf Leipzig], [https://wikis.hu-berlin.de/interlinear_glossing/Glossing_Rules Humboldt]) and they both specify left-alignment for the interlinear items. -- [[user:Mirokado|Mirokado]] ([[user talk:Mirokado|talk]]) 22:44, 30 January 2024 (UTC)

:::Basically, I think ''something'' about the right-to-left version should visually signal that this is right-to-left. If the overall gloss hugs the left edge of the page (per the <code>table</code> thing), then I think the words should align right within the blocks. Or if not that, then ''something'' should align right to make it visually clear. [[User:Eievie|Eievie]] ([[User talk:Eievie|talk]]) 01:21, 31 January 2024 (UTC)
:::: Yes, that is a good point. It is particularly noticeable in the Cypriot example. So please go with right-aligned words within the blocks. -- [[user:Mirokado|Mirokado]] ([[user talk:Mirokado|talk]]) 11:58, 1 February 2024 (UTC)

=== Box width, margin spacing ===
In various examples already provided for this change, some lines which are not word-split for the table columns are separated from the table by their alignment to the page margins. This impairs readability and is not good graphic design. It should be corrected by an enclosing box (or whatever depending on implementation) whose width is related to the width of the main table. It would be fine to have left- and/or right-padding for the table to provide a small (say 3em) offset for the margins of the lines outside the table. -- [[user:Mirokado|Mirokado]] ([[user talk:Mirokado|talk]]) 17:19, 29 January 2024 (UTC)

:Can you provide an example? I can't quite imagine what you mean by "some lines which are not word-split". Are you referring to Phoenician examples that use dots, rather than spaces, as word delimitators?
:As for box width:
:# Right now the box has the default <code>&lt;div&gt;</code> property: <code>display: block;</code> which takes 100% width.

:: In your original examples, you had a top line with the original script, and all examples have the bottom line with the English translation. Depending on the various alignment choices, one or other of these could end up separated from the interlinear lines which are shorter than the margin separation for a wide screen (less noticeable on a narrow screen).{{pb}} Your final example here using <code><small>display: table;</small></code> is what I was looking for. It behaves nicely as the window is made narrower. Well done!

== Highlighting foreign language text as in template:lang ==
I think it is desirable to apply the same markup to the foreign script in this template as is applied by {{tlx|lang}}. In my view this would be necessary if we are to use this template in articles where all the foreign script is already presented via the lang template(s). The relevant language can already be specified by {{para|lang}}, so not providing this markup may go against a user's expectations. -- [[user:Mirokado|Mirokado]] ([[user talk:Mirokado|talk]]) 17:19, 29 January 2024 (UTC)

:I think this should go beyond just {{tl|lang}}, to a broader feature where we can wrap each word of <math>n</math> line in <math>x</math> template. It could default to:
:* {{tl|fs interlinear}}
:*# line 1: {{tl|script}}
:*# line 2: {{tl|transliteration}}
:* {{tl|interlinear}}
:*# line 1: {{tl|lang}}
:but alterable with additional parameters, just as the default italics and glossing can be altered. [[User:Eievie|Eievie]] ([[User talk:Eievie|talk]]) 17:18, 30 January 2024 (UTC)
::Yes, by all means consider a broader feature. You are right that {{tlx|lang}} markup is only relevant for the original-language line. As far as I can see, lang should be used for line 1 in both the above cases when that line is in a particular language. -- [[user:Mirokado|Mirokado]] ([[user talk:Mirokado|talk]]) 22:58, 30 January 2024 (UTC)

== Template overhaul ==

In the file [[Module:Interlinear/sandbox2]], I have been working on a substantially changed version of the Lua code. Testing/examples of it can be seen on [[Template:Interlinear/sandbox/testcases]].

The main categories of changes are:

# Moving as much of the CSS code as possible out of the Lua file and into the file [[Template:Interlinear/sandbox2/styles.css|../styles.css]]. Having the CSS code in one place and controlled by classes (rather than <code>style=</code>) makes it cleaner and easier to alter.
# Adding the right-to-left {{para|rtl|yes}} feature
# (in progress) Integrating the use of other Wikipedia templates into interlinear glosses, namely: {{tl|script}}, {{tl|lang}}, {{tl|transliteration}}, {{tl|IPA}}. Ideally there would be a parameter along the same lines as {{para|italics<math>n</math>|yes}} — perhaps {{para|wrapper<math>n</math>|}} — which would allow a user to specify a template to apply to each word of a line.
# Creating a {{para|smallcaps|yes}} parameter, as it appears that many people like to format transliteration of inscriptions that way (particularly the Phoenician and Ogham ones)
# (to do) Clean up the glossing code somehow. Move it to a second module, which is called upon? Not sure what yet, but right now it's the least readable part of the file and it's driving me slightly crazy. Within the broader category of integrating other templates into it, I'm thinking about some form of creating a separate {{tc|gcl}} template or module which is called upon.
